Data exchange method and data exchange intermediate device

Abstract

The invention provides a data exchange method. The data exchange method includes the steps that regulation description files of different application programs are loaded, the regulation description files comprises database information, database source lists, database target lists and database filtering conditions; the database information, the database source lists, the database target lists and the database filtering conditions are analyzed; the database source lists of the different application programs are inquired; data of the database source lists of the different application programs are filtered according to the database filtering conditions of the different application programs; the filtered data are stored in the database target lists of the different application programs respectively. The invention further provides a data exchange intermediate device. By means of the data exchange method and the data exchange intermediate device, the different application programs are allowed to use a uniform service logic visit database and generate data required by the different application programs, function reuse is achieved, the complex rate of developing work is reduced, the coupling relation between the different application programs and the service logic of the different application programs and data sources can be relieved, a system is allowed to further possess expansibility, and changeful application requirements are met.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a data exchange method and a data exchange intermediate device of an integrated multi-application system. Background technique [0002] The current integrated multi-application system collects the data collected by the deployed field devices into the background database of the system, and the application software accesses the database according to the business logic of the application and pushes information to the client. With the change of application requirements, the business logic becomes richer and more complex. The way a single application software handles multiple businesses is inflexible and difficult to adapt to the development of the application. The way multiple applications run their own business logic and access the database faces many challenges Investing in feature duplication development. [0003] To sum up, there are at least the following problems in the e...

Problems solved by technology

[0004] In order to overcome the problems in the prior art that multiple applications run their own business logic and access the database, resulting in repeated development, different applications cannot use unified business logic to access the database, and cannot achieve functional reuse and reduce development work. Embodiment 1 of the present invention Aspects provide a data exchange method that includes:
